    No, a nightmare of a y pipe leading to a single cat and dual tips on the driver's side. Is it carb or cfi?

    Ahh... that may have had a second cat on the y pipe if I remember correctly it did. Does it still have the stock exhaust manifolds? If so I would toss em, get some shorty headers that don't hit the steering knuckle and buy a nice aftermarket dual setup, cause you can't get the stock y from anywhere and the stock manifolds have that stupid heat crossover valve that won't let you hook up aftermarket 86 duals (which you can buy).

    Only other thing to worry about after that is your fuel line, a dual exhaust cross-member for the transmission (cheap and nice from cjpony), and the rear brake line going to the axle.

    The y pipe is really going to make it hard to go back to stock single exhaust if you wanted that.

    Depending on your states requirements you may want to go with a complete new system (headers to tailpipes). They are much easier to install (new hardware) and fit great. If you need 2 new cats it will be pricey though. Don't forget the right side exhaust hanger that goes aft of the wheel.

    ???? The last new Cat I bought was about 3 years ago and it was a 2 1/2 inch MAC High Flo and was like $60?
